one day i noticed that my car was running better than it was the day before, and i had no idea why i was pretty stumped on why it felt better... but my friends came up with a funny theory, lol. i lent my friend the car (he gave me $50 bucks and filled the car up with gas, lol) and he went out with some friends and hot boxed in my car... maybe my iroc likes to be blazed in? lmfao, i dunno, but anyway...

either your fuel injectors WERE clogged and now they're not... or your ECM is advancing the timing to a better place... maybe your timing was too high or too low... but i'd be happy your car is running better might have to do with the weather... you never know.
